Roof coatings are performed by the same roofing contractors that install, replace and maintain roofing systems, so the process of finding and choosing a reliable one is always the same. Although applying a roof coating is not necessarily complicated, you need good professionals to ensure that you get proper warranties and to help you navigate through the various choices you have when it comes to roof coatings, The product you choose must be suitable with the local climate, your purpose (waterproofing the roof or making it more reflective) and some other important variables such as weather extremes in the area and the condition of the existing roof etc.
When you evaluate different roofing contractors, check for credential first and ask to see the certificates. License and insurance are mandatory.
You should opt for a local roofer, because it will be easier to communicate directly and keep in touch in case of future problems. Besides, a local roofer is prompter in providing emergency services when you need them.
Different Denver commercial roofing companies typically have different offers, but you should avoid considering the price as the only factor that matters. Cheap bids are not always based on quality.
Finally yet importantly, get everything in writing, before signing any contract.
